BACKGROUND OF THE INVENTION This invention relates generally to thefield of tubing operator apparatus and more particularly to aremotecontrolled tubing operator apparatus for effectingremote-controlled operation of a through-the-bore movable flowcontrolling valve means at a subsurface location in a well.

Wire-line or through-the-bore retrievable safety valve means forcontrolling flow in a well tubing at a subsurface location and which areoperated from a remote location such as disclosed in US. Pat. Nos.3,667,505; 3,078,923; 3,696,868 and Re. 26,149, are known. These valveswere operated by control fluid pressure communicated from the surfaceinto the valve means by small control fluid conduits which were run inthe well when the production tubing was set. Frequently, these safetyvalve systems were rendered inoperative by foreign matter plugging thesmall control fluid conduits which were exposed to well fluid whenrunning or retrieving the safety valve or by various failures of theconduits to communicate the control fluid pressure required to operatethe valve. The control line plugging problem was especially critical intwo control line balanced safety valves, such as disclosed in US. Pat.Nos. 3,077,669 or 3,411,576, which could be rendered inoperative by theplugging or failure of either control fluid line. The necessity to pullthe production tubing to repair the control system was particularlyundesirable due to the cost involved in performing that operation andthe risk of damage to the producing formation that could result in losthydrocarbon production.

while the inventions disclosed in my related copending applicationsidentified hereinabove have served to reduce the opportunity forplugging of the small condiuts, a conduit failure would still limit thecapability of those valves to control undesired flow.

FIG. 3 is a side view, similar to FIG. 2, with the operator apparatusillustrated prior to operation.

DESCRIPTION OF THE PREFERRED EMBODIMENT The operator apparatus of thepresent invention is generally designated A in the FIGS. and ispreferably mounted with or made up in a flow conduit or well productiontubing, designated at T, a subsurface location below the well headapparatus or christmas tree, generally designated X, for effectingoperation of a flow control means for shutting-in or controlling flow inthe well at the subsurface location. Of course, the operator apparatus Amay be mounted with any flow conduit for effecting operation of the flowcontrol means to control the flow of fluids through the conduit and thepresent invention should not in any manner be considered limited to usein wells.

In FIG. 1A, the christmas tree X is illustrated located immediatelyadjacent ground surface S, but the tree X may be located above thesurface S, for example, on a structure such as an offshore platform (notillustrated) that will locate the tree X a considerable distance fromthe ground S as is well known. With such an arrangement the operatorapparatus A could be mounted in the tubing T above the surface S, butsubsurface location is preferred for numerous well-known reasons. Apacker (not illustrated) may be employed below the apparatus A to directthe flow of produced hydrocarbons through the bore of the productiontubing T as is well known in the art.

The operator apparatus A includes a tubular member or flow housing Hhaving a longitudinally extending bore B formed therethrough which isaligned with and in communication with the bore (not illustrated) of theproduction tubing to provide a flow passage for well fluids and the likethrough the housing H as is well known. The housing H preferablyincludes an upper threaded box connection (not illustrated) and a lowerthreaded pin connection (not illustrated to enable the housing H to bemade up in the production tubing as is well known in the art. For easeof assembly, the housing H is formed of an upper sleeve member 10secured to an intermediate sleeve member or section 11 by suitable meanssuch as threaded engagement at 12 (FIG. 1A) and as illustrated in FIG.llC, the sleeve member 111 is secured to a lower sleeve member orsection 13 by suitable means such as threaded engagement at 14. Thehousing H further includes an inner sleeve 15 mounted with the sleeve 13by suitable means, such as threaded engagement at 16, and which extendsupwardly in concentric spaced relationship with sleeve 11 to an upwardlyfacing annular shoulder 15a (FIG. 1B).

3 A pair of O-rings, 17a and 17b block leakage of fluid by the threadedengagement at 12 while O-rings l8 and 19 block leakage of fluid by thethreaded engagement 14 and 16 (FIG. 1C), respectively. Suitable antirotation pins (not illustrated) may be utilized to prevent inadvertentdisengagement of the threads 12, 14 and 16 as is well known in the art.

The operator apparatus A includes a tubular operator member or means 20movably mounted with the sleeve 11 and which operator member 20 isadapted to co-act with a received flow control means to control flowthrough the bore B in response to movement of the operator 20. Thetubular operator member 20 extends downwardly from an upwardly facingannular shoulder 20a (FIG. 1A) to a downwardly facing annular shoulder20b located in the annular area between the spaced housing sleeves 11and 15. The operator 20 is longitudinally movable in the bore B to andfrom an upper or first position (FIG. 3) for blocking flow through thebore B with the flow control valve means and a second or lower position(FIGS. 1A, 1B and 2) for operating the flow control means to enable flowor production of well fluids through the bore B of the housing H.

The operator assembly A of the present invention is designed andarranged to receive, locate, secure, operate and release the flowcontrol valve means of the type disclosed in my co-pending applications,identified hereinabove as related copending applications, and to whichspecific reference is hereby made for incorporating the disclosure ofthose applications herein. Those applications set forth in detail themethod and apparatus used in running the flow control valve meansthrough the bore of the tubing T to the subsurface location of theoperator apparatus A where it is to be secured and utilized to controlflow in the bore B of the housing H and in retrieving the flow controlvalve means from the housing H when desired.

Briefly to assist in understanding the present invention, the flowcontrol valve means which is partially illustrated in FIGS. 1A and 1B,and generally designated V, moves through the bore of the tubing T intothe aligned bore B of the housing H where the valve means is receivedfor securing against movement by a plurality of latch dogs 100 locatedin a plurality of circumferentially spaced window openings 101 formed ina tubular valve frame or body 102 (FIG. 1A) of the flow control valvemeans. The latch dogs 100 move radially outwardly into an annular recessa formed in the inner surface 10b of the sleeve 10 for securing thevalve means frame 102 with the housing H. As illustrated in FIG. 1B, theflow control valve meansV includes a tubular operator member 103 havinga plurality of circumferentially spaced windows or openings 104 formedtherein having a corresponding plurality of latch dogs 105 positionedtherein which move radially outwardly into an annular recess 200 formedin the inner surface d for operably securing the flow control valvemeans operator 103 with the operator 20 of the apparatus A. The flowcontrol valve means V further includes latch sleeves 106 and 107 forholding or locking the radially expanded latch dogs 100 and 105,respectively, for securing the valve means V in the operator apparatus Aand for co-acting with the operator member 20 for controlling flow offluid through the bore B. The flow control valve means V furtherincludes a rotatable ball bore closure means (not illustrated) which ismoved to the closed position to block flow when the flow control valvemeans operator 103 is longitudinally moved toward latch dogs by theoperator 20 moving to the upper position (FIG. 3) and which rotates tothe open position to enable flow when the operator 103 is moved in adirection away from the latch dog 100 when the operator 20 moves to thelower position (FIGS. 18 and 2).

The lower sleeve 13 of the housing H provides an upwardly facing annularshoulder 13a (FIG. 1C) between the sleeves 11 and 15 which mounts aspring or urging means 21 which engages the annular shoulder 20b of theoperator 20 at an upper end for urging the operator sleeve 20 to theupper position (FIG. 3). Thus, the spring means 21 urges the operator 20to move up wardly for blocking flow through the bore B with the flowcontrol valve means operably secured with the ap paratus A.

The operator 20 mounts an annular sealing element or chevron packingadjacent the lower annular shoulder 20b for effecting a sliding annularseal with an outer surface 15b of the sleeve 15 to block leakage offluid therebetween. The sleeve 11 mounts an annular sealing element orchevron packing 23 adjacent the upper shoulder 20a for effecting anannular sliding seal between the sleeve 11 and an outer surface 202 ofthe operator 20 to block leakage of fluid therebetween. The outersurface 20e is formed to provide an upwardly facing tapered annularshoulder 20fbelow the seal of the chevron packing 23. The operator 20mounts an O-ring 24 in an annular recess formed in the surface 20e belowthe shoulder 20ffor effecting a sliding annular seal between theoperator 20 and a sealing surface 11a of the sleeve 11 to block leakageof fluid therebetween.

The operator apparatus A may also include a movable landing member orelement 29 for locating the received flow control valve means V in thebore B for operably securing therein to control the flow of fluidthrough the bore B. The landing member 29 is preferably an expansiblering member having a gapped opening to enable contraction thereof andwhich is positioned adjacent a downwardly facing tapered annularshoulder 20g formed by the inner surface 20d of the operator 20. Asillustrated in FIG. 3, when the operator 20 is in the upper position,the landing ring or member 29 is in a first or radially expandedposition for providing a full bore opening B through the housing H toenable the running of well tools and others through the bore flowcontrol means through the apparatus A as desired. The landing member 29includes an upwardly facing tapered annular shoulder 29a adjacent theshoulder 20g and a downwardly facing tapered annular shoulder 29b forengaging the upwardly facing tapered annular shoulder 15a when theoperator 20 moves to the lower position for moving or forcing thelanding ring 29 inwardly to a radially contracted or second position toconstrict the bore B and provide a landing stop to locate or positionthe flow control valve means V for securing with the housing H to co-actwith the operator 20.

The operator apparatus A includes a first control means and a secondcontrol means which are independently operable to overcome the upwardlyurging of the spring 21 to move the operator 20 to the lower positionfor effecting operation of the flow control valve means or to move thelanding member 29 to the second position for providing a landing stopfor the flow control valve means. Should either the first or the secondcontrol means be rendered inoperative for any reason, the remainingoperative control means will continue to function to operate theapparatus A independently of the inoperative control means. The housingH further includes a movable piston ring 30 (FIG. 1B) movably disposedbetween the sleeve 11 and the operator 20 below the packing 23. Thepiston 30 includes an inner surface 30a mounting an O-ring 31 thereinfor effecting a sliding annular seal between the piston 30 and the outersurface 20:2 of the operator 20 to block leakage of fluid therebetween.The sleeve 11 includes a second inner sealing surface 11b which effectsa sliding seal with an O-ring 32 mounted in an annular recess in anouter surface 30b of the piston 30. The piston 30 includes a beveleddownwardly facing annular shoulder surface 30c and an upwardly facingbeveled annular shoulder 30a which engages a downwardly facing annularshoulder 100 provided by the sleeve to provide an upper limit stop tothe piston 30 in the first or upper position as illustrated in FIG. 3.The annular shoulder f of the operator 20 engages the downwardly facingshoulder 3tlc of the piston for providing an upper limit stop to theoperator 20. When the piston 30 moves to the lower position (FIG. 2) theengagement of the shoulder 300 with the shoulder 20fmoves the operator20 to the lower position also.

The first control means includes a first or normal operating expansiblechamber 40 which is formed between the sleeve 11 and the operator 20below the piston 30, and above the seal of the O-ring 24. As illustratedin FIG. 1B, fluid pressure in the chamber 40 will urge upwardly on thedownwardly facing annular shoulder surface 300 of the piston 30 betweenthe seals effected by the O-rings 32 and 31 for moving the piston 30upwardly. Fluid pressure in the chamber 40 will also urge downwardly onthe annular shoulder 20f on the pressure responsive effective surfacearea between the seals effected by the O-ring 31 and 24 for moving theoperator 20 to the lower position for enabling flow.

The sleeve 11 and the operator 20 are also arranged to form a secondexpansible chamber 41 (FIG. 2) above the piston 30 which is included inthe second control means. Fluid pressure in the second expansiblechamber 41 will urge downwardly upon the upwardly facing annularshoulder 30d between the seals effected by the O-rings 31 and 32 forurging piston 30 to move downwardly to the lower position.

The operator 20 and the housing H also arrange to form a thirdexpansible chamber 42 defined by the seals effected by the O-ring 24 andthe chevron packing 22. Fluid pressure in the expansible chamber 42urges upwardly on the downwardly facing annular shoulder 2012 over a netpressure responsive effective surface area between the seals effected bythe chevron packing 22 and the O-ring 24. The operator 20 is spaced fromthe sleeve 11 when the operator 20 is in the upper position (FIG. 3) toenable communication between the second expansible chamber 41 and thethird chamber 42 through a flow channel 43 formed in the sleeve 11. Withexpansible chambers 41 and 42 in communication by the flow channel 43,the control fluid pressure is the same in both the chambers 41 and 42,but as the upwardly facing net pressure responsive surface area 30d ofthe piston 30 is greater than the downwardly facing net pressureresponsive surface area of the shoulder 20b, a net downward force formoving the operator 20 to the lower position results from increasedcontrol fluid pressure in the chambers 41 and 42. Thus, the secondexpansible chamber 41 includes the third expansible chamber 42.

In addition to the first expansible chamber 40 arranged in the housing Hfor urging movement of the operator 20 to the second position, the firstcontrol means includes a first control fluid passage 44 communicatingthe chamber 40 with a first control fluid conduit 45 (FIG. 1A) whichcommunicates with a source of control fluid pressure 46 at a locationspaced from the housing H to provide remote controlled operation of theoperator apparatus A.

The second control means includes a second source of control fluid 47spaced from the housing H which communicates with the second expansiblechamber 41 and the chamber 42 through a second control fluid conduit 48and flow passages 49 and 50 formed in the sleeves 10 and 11,respectively. Such sources of control fluid pressure are well known inthe art and may be manual, automatic or a combination thereof for remotecontrol operation of the apparatus A. The source of the control fluidpressure 46 and 47 are illustrated positioned on the surface S adjacentthe tree X, but they may be positioned at a location spaced from eitheror both the surface S or the tree X. While the disclosed first andsecond control means utilize control fluid pressure to operate theapparatus A, other suitable means such as, but not limited to, insulatedelectric conductors, may be used to remotely control operation of theapparatus A and flow through the bore B.

In the use and operation of the present invention, the housing H is madeup in a production tubing for positioning at the desired subsurfacelocation. Control fluid conduits 45 and 48 are connected and theapparatus A lowered in the well until it is positioned at the desiredsubsurface location. The sources of contol fluid pressure 46 and 47 arethen connected to the fluid conduits 45 and 48, respectively, foreffecting desired operation of the apparatus A.

Preferably control fluid pressure in the chamber 40 is then increased byoperation of the source 46 with the increased control fluid pressurecommunicated through the conduit 45 and the flow passage 44 into thechamber 40. The control fluid pressure in the chamber 40 urgesdownwardly upon the upwardly facing annular shoulder 20f to move theoperator 20 from the upper position (FIG. 3) to the lower position (FIG.1B) which moves the landing ring 29 inwardly where it will engage alower annular shoulder 107a of the lower latch 107 of the flow controlvalve means V. The flow control valve means V moves through the bore ofthe production tubing T to the apparatus A where it is secured againstmovement in the bore B by the latch dogs and operably secured with theoperator 20 by the latch dogs for effecting operation of the flowcontrol valve means as set forth in greater detail in my copendingapplications identified hereinabove.

Should it become desirable to operate the apparatus with other than thefirst control means which may be occasioned by the plugging or rupturingof the conduit 45, the second control means may be employed to move thelanding member 29 inwardly to provide a landing stop for the flowcontrol valve means. The control fluid pressure in the chambers 41 and42 is increased to move the operator 20 to the lower position (FIG. 2)by operation of the source 47 in the well known manner. Thus, it isapparent that the landing member 29 is operable to the second positionby either the first or the second control means and such operation isindependent of the other control means.

To enable flow through the bore B of the housing H by the flow controlvalve means, the operator member is moved to the lower position byincreasing the control fluid pressure in the expansible chamber 40 bythe first control means or by increasing fluid pressure in the chambers41 and 42 with the second source of control fluid 47. When the controlfluid pressure in the chambers 40 and 41 and 42 is reduced, the spring21 moves the operator 20 to the upper position for effecting closure ofthe flow control valve means V to block flow of fluid through the bore Bin the housing H at the subsurface location. Such an arrangementprovides for failsafe operation in that loss of control fluid pressurewill shut-in the well.

For normal operation of the apparatus A the use of the first controlsource 46 is preferred in that downward movement of the operator 20 byincreased pressure in the chamber 40 enables egress of fluid from thechamber 42 below the operator 20 through the flow passage 43 and theconduit 48 back to the second source 47 at the surface as the operator20 moves down. The arrangement of the chambers 40, 41 and 42 is thus toenable the static hydraulic head of the control fluid in the conduits 45and 48 to be substantially balanced on the operator 20, as is well knownin the art, for enabling the location of the operator apparatus A atgreater well depths with the spring 20 operable to close the valvewithout overcoming the static head. This arrangement also reduces theeffect of the well pressure in the bore B urging upwardly on thepressure responsive net effective surface area of the shoulder 20gbetween the seals effected by the chevron packing 22 and 23 tosubstantially provide a well pressure balanced operator 20 to reduce themagnitude of the control fluid pressure required to move the operatordownwardly to operate the flow control valve means.

The flow control valve means may be retrieved and replaced wheneverdesired without the need to kill the well and pull the production tubingT.
